Direct answer

An international migration is a set of locale-specific moves, not one global redirect list. Inventory every eligible source URL, decide its market/language destination or retirement individually, and validate canonical, redirect, internal-link and hreflang relationships as one connected graph. Sequence the work through gates — scope freeze, destination decisions, staging, testing, approval, an authorized launch, and post-launch monitoring.

Key takeaways

  • An international migration is locale-specific, not one global redirect list.
  • Validate canonical, redirect, internal-link and hreflang together as one graph.
  • Resolve one-to-one, consolidation, split and retirement decisions before staging.
  • Test representative, high-value, and edge-case URL graphs before launch.
  • Launch only under a separately authorized runbook, then monitor and diagnose.

Why one redirect list is not enough

An international migration is a set of locale-specific moves, not one global redirect list. Inventory every eligible source URL, decide its market/language destination or retirement, and validate canonical, redirect, internal-link and hreflang relationships as one graph.

Locale Migration Ledger

Minimum fields: source URL/status; language/locale/market; current canonical; hreflang cluster; traffic/link/reference importance; destination decision; destination URL; content parity; redirect recommendation; new canonical; reciprocal alternates; sitemap/internal links; owner; test evidence; launch state and rollback.

Seven gates

  1. Freeze scope and benchmark locale cohorts.
  2. Resolve one-to-one, consolidation, split and retirement decisions.
  3. Stage complete localized content and annotations.
  4. Test representative, high-value and edge-case URL graphs.
  5. Obtain technical, locale and business approval.
  6. Launch only under a separately authorized runbook.
  7. Monitor crawl/indexing, errors and cohort performance; diagnose before changing the plan.

Google recommends mapping old URLs to new ones and using server-side permanent redirects for permanent moves.

For localized pages, each language version should list itself and the other versions via hreflang, and canonicals used with hreflang should normally point to the same language version.

Taskcover can help plan and validate an international migration ledger before any redirects go live.

Can one global redirect list cover an international migration?

Not reliably. Each locale URL needs its own destination decision, and canonical, redirect, internal-link and hreflang relationships need to be validated together as one graph.

Should a canonical point to a different language than the page itself?

Generally no. Canonicals used with hreflang should normally point to the same language version, per Google's localized-versions guidance.

When should an international migration actually launch?

Only under a separately authorized runbook, after technical, locale and business approval, with representative and edge-case URL graphs already tested.

Migrate international URLs without breaking locale relationships.

Taskcover can help build a locale migration ledger and validation gates before launch.
